Bug 1994341 [wpt PR 55441] - [anchor] Fix anchored-fallback-scroll.html, a=testonly
Automatic update from web-platform-tests
[anchor] Fix anchored-fallback-scroll.html
This testcase was created assuming that the containing-block rectangle
was the viewport, not the scrollable rect.
Switch to `position:fixed` such that it uses the viewport.
